	<h3>Senior 4</h3>
	<h2>TOPIC2: FUNCTIONS AND ALGEBRA</h2>
	<h3>Subtopic 1: introduction to functions</h3>
	<h3>Video: introduction to functions</h3>

	<h4>Description</h4>
	<p>This video shows the introduction to function and takes 13 minutes and 07 seconds.</p>

	<h4>Orientation</h4>
	<p>This lesson should be tough in senior 3</p>

	<h4>Educational approach or Methodology</h4>
	<p>By the end of the series learners should be able to represent a number pattern in a table, a flow diagram, a formula or a graph. They should also be able to draw conclusions about the properties of functions and their graphs. In the National Curriculum Statement, the new approach to studying functions encourages learners to do investigations in order to build their own understanding.</p>
	<p>We start by establishing a pattern of numbers, which we investigate. From there we develop a formula, and then we look at function notation. Although learners need not know the specific function notation that is explained, it is useful to show them a correct way to refer to specific variables and function rules. Then we study the general properties of the functions and how to interpret graphs.</p>
	<p>The section on function notation in lesson 4 could be used as enrichment. We also use the circle and semi-circle as tools to demonstrate some concepts. Remind learners to focus on the concept, rather than the tools that are used to illustrate the concept.</p>
	<p>In the eighth lesson, graphs are transformed in different ways. This concept is useful across other areas of mathematics, particular mathematics.</p>
	<p>In the lessons, we also encourage learners to estimate and to do mental arithmetic, and then find the exact answer using a calculator.</p>
	<p>To get the full benefit of the lessons, your learners need to engage actively with the concepts presented. So, when you preview the videos, think about how to introduce each lesson and what follow up activities will be useful. Also watch out for places in the video where you can pause to have a class discussion, or ask learners to complete an activity or solve a problem posed in the video. We have used this pause icon to suggest some of these places to you.</p>
